HS students taking physics?
10 Reasons Why High School Students
Should Take Physics
Inland Empire HS Physics enrollments lag
State by 2X and lag nation by 3X
1. Physics is a core science
discipline
Physics with Biology and Chemistry are the 3
Fundamental “Core” Science Disciplines
Your view of the world, nature, and how things work are
incomplete without a knowledge of physics…as incomplete as
if you skipped biology or chemistry
Physics, more than the other 2 core sciences, uses
mathematics and computing which give it a precision,
predictive power, and simulation power, that are
unprecedented in human history
All other science and engineering are based on biology,
chemistry, physics and math—physics is required for all
science and engineering majors in college
You are at an advantage if you have had a high school course in
Physics
Physics should be the 3rd
science course taken in HS
Physics is a CORE discipline: ALL science is
based on 4 pillars: Math, Biology, Chemistry
and Physics
UC requires 1 Life Science and 1 Physical
Science and recommends a 3rd year of HS
Science. Students are advised to take Biology,
Chemistry…. 3rd choice should be PHYSICS.
Physics is accepted as 3rd science course by UC
Anatomy, Physiology, Earth Science are not core
disciplines
2. Most modern technology
involves physics.
Any technology involving electricity,
magnetism, force, pressure, heat, light,
energy, sound, optics, etc. comes from
physics.
Basic knowledge required for products like
fertilizers, drugs, plastics, and chemicals
comes from chemistry and biology, these
items have to eventually be manufactured,
and manufacturing is dominated by physicsbased technology.
3. HS Physics is the Gateway to
Physics, Engineering, and
Computing Jobs and Careers
Physics along with Biology and Chemistry are
the 3 Core Science Discipline
All 3 use math, but Physics uses math and
computing more
Engineering is based on Applied Physics
HS Physics begins training students in
quantitative science, applied math, and
problem solving
4. The job market for people with
skills in physics is stronger than for
skills in biology and chemistry
Engineers are applied physicists and
comprise the second largest profession in
America (second only to teaching) with about
1.4 million members. By comparison, there
are about 600 thousand medical doctors and
only around 100 thousand biologists.
STEM Careers are dominated by
Physics and Computer
1.65M
3.1M
Engineering and Computer
Science sectors > Life
Science/Chemistry sectors
1.1M
0.7M
Compare to other sectors: earth
science, social science, math
5. Physics is required in college
level science—student is at
disadvantage without HS Physics
1 year of college level Physics is required for
all other science majors
At UCR Life-Science Physics is Calculusbased
It is a gateway to upper division majors in
biology, chemistry, earth science,
environmental science, entomology,
biochemistry, mathematics, statistics
Example: HS Physics is Important
for Life Science Majors
All College Science Majors require a minimum of 1 year of College
Physics—in UC this is a Calculus-Based Physics Course
Life Science majors take:
Freshman:
1 year of Calculus
1 year of General Chem
Sophomore:
1 year of Organic Chem
1 year of Intro Biology
1 year of Physics (Calc based)
Junior:
1 year of Biochemistry
Lower Division Requirements include Physics before moving into a
specific biological major
Junior Transfer students must have completed Physics with a
minimum GPA requirement

6. Physics classes help polish the
skills needed to score well on the
SAT.
Physics classes provide practice in both
algebra and geometry. These are the types of
mathematics most likely to occur on the SAT.
To work physics problems, students must be
able to read and comprehend short
paragraphs then develop problem solving
strategies from them. Physics helps develop
both math and verbal skills.
Physics is a whole brain subject requiring
students to use both right and left brain
regions for translating complex verbal
information into pictures and finally into
mathematical models in order to solve
problems.
7. College recruiters recognize the
value of physics classes.
College recruiters tend to be favorably
impressed by transcripts containing
challenging classes like physics. They know it
is relatively easy to attain a high GPA by
taking a light course load. Some technically
oriented college programs will deny entrance
to students who have not taken high school
physics.
8. A knowledge of physics is
helpful for understanding the arts.
Physics is the science of sound and is needed for
understanding how musical instruments work.
Physics is also the science of light and is key to
understanding visual artwork including paintings,
photograph, stage lighting, filmmaking, etc.
Even literary works have been influenced by
physics. William Faulkner, for example, used the
symbolism of time dilation in The Sound and the
Fury. Many commonly used expressions in everyday
language come from physics, including quantum
leap, free fall, light years, black holes, resonance,
and being on the same wave length.
9. Physics leads to a better
understanding of politics, history,
and culture because technology is so
important.
Supply and use of water, energy resources,
technology is the basis for civilization
Competition for Resources, Defense and
Military technology have shaped history (iron
age, bronze age)
Quantum Mechanics and Relativity 20th
century
Global warming
10. Physics offers a deep and
unique perspective in itself
Physics has set the “scientific method” and has
the most stringent requirements for hypothesis
and test of hypothesis. Physics theories are not
only tested 1000’s of times but a single contrary
experiment can force the change of a theory
Classical Physics fell from 3 experiments
Photoelectric effect, black body radiation spectrum, spectral
lines from atoms
The (Accelerating) Expansion of the Universe signals
a new Physics to include Dark Energy and Dark
Matter
Summary of STEM job future
1.5X more Physics-Related jobs than Life
Science-related
3X more Computer-Related jobs than Life
Science-related
Life Science and Chemistry jobs are 30% of
STEM total
HS students who don’t take Physics are
unlikely to pursue the majority (70%) of
STEM careers

Lack of US-trained engineers has forced
hiring of large numbers of foreign-trained
engineers. Engineering BS and PhD have
excellent job prospects

Impact to IE Youth
3X lower access to high tech education, jobs,
and careers than national average
Less competitive for better 4-year colleges
which look favorably on harder college prep
Lack experience with quantitative science,
applied math, physical intuition and technical
problem solving
Quality of HS Physics teaching is lower
because teachers do not teach Physics full
time
Why College Bound need
HS Physics
All Science and Engineering students must
take and pass College Physics
Premeds-Biology majors need to take Physics 2nd
year…at all UC’s Physics is Calculus-based
Engineers-Chemistry-Physics majors must take
Calculus-Based Physics freshman year
Students are less likely to do well in College Physics
if they have not taken HS Physics
Why College Bound need
HS Physics
Non-science/engineering majors must take 1
Physical Science course—combined with HS
Chemistry and HS Physics….barely sufficient
for careers in technology sector in
administration, sales, repair and service. HS
Physics could be a significant fraction of total
Physical Science education.

7. College success for virtually all
science, computing, engineering, and
premedical majors requires passing
physics.
Engineering is largely applied physics.
Pre-medicine majors typically must take a 1 year course
in Physics. About 25% of the science knowledge
required for the MCAT (Medical College Admission Test)
is based on physics. Studies indicate that a high quality
high school physics course helps significantly reduce the
failure rate in college-level physics. Students themselves
typically indicate that high school physics is a significant
factor in their ability to handle college-level physics
material.
